Railway-car-roof construction.



E. W. SUMMERS. RAILWAY GAR ROOF CONSTRUCTION. APPLICATION FILED SEPT-.23,1913.

Patented Mar. 30, 1915.

from creeping upwardly by capillary attraction. These flattened out end portions 10 fit snugly against the car roof, and the joints between the same and the roof sheets,

such as at the points 12, can be filled with paint, asphaltum or the like so as to shed the water and cause the same to run off at the sides instead of between the ends of the cover strip and the roof sheets.

Fig. 6 shows a modification in which the cover strip 8, instead of being a separate piece, is-an extension of one of the flanges 6* of one of the roof sheets. In other particulars this is the same as the main form.

. The inwardly extending flanges 13 of the eaves plates 3, it will be observed, fit snugly against the inner 'faces of the roof sheets and conform to the contour thereof, instead of extending inwardly horizontally, as is usual in car constructions. As a consequence the roof sheets are supported inwards from the caves, and any water that might find its way upwardly by capillary attraction is more likely to flow downwardly and .outwardly than upwardly and inwardly.

The roof construction described is such that there are no holes or openings from the outside inwardly. All of the securing members or "rivets are horizontal, and extend merely through the up-standing seams of the roof plates. Ihese upstanding seams also provide convenient means for connect-- ing to the roof the clips for supporting the running boards, guard rails and the like without puncturing the roof plates themselves. As a consequence the roof canbe made perfectly waterproof or tight. Fur thermore, the construction is such that there are no internal carlines, thus giving clear head-room within the car, and at thesame time the roof is entirely selfsustaining by reason of the external car lines formed by the joints or seams, and their connections to the side plates. Wear and-tear upon the roof sheets is lessened by theoutside 'carlines because of the support which they afiord to the roof sheets from eaves to eaves at their meeting edges, and because of the rigid connection between the ends of the carlinesand the side plates, and the form of the side plates.

What I claim is:

1. In a car roof, the combination of adjacent metallic roof plates extending transverselyo'f the car "from eaves to eaves and providedon their adjoining edges with external vertical flanges, and a U-shaped cover strip fitting over said flanges and rlgidly se cured thereto throughout its length, the ends of said-coverjstrip being spread out and extending over the caves and secured at their lower ends.

2. In a car,'the combination with the side plates of adjacent metallic roof plates extending transversely ef the ear and --su-prigidly secured thereto throughout their length, the ends of said cover strips extending over the eaves and being secured at their lower ends to said side plates.

3. In a car, the combination with the side 1 plates of metallic roof plates extending transversely of the car and having downturned end flanges and upturned side flanges, said end flanges being secured to said side plates, and said side flanges extending uninterruptedly from side to side of the car and having cover strips rigidly secured thereto throughout their length forming carlines, the ends of said cover strips being turned down over the eaves and secured to said side plates.

4. In a car, the combination with the side plates of metallic roof plates extending transversely of the car and provided on their adjoining edges with external vertical flanges, said flanges extending uninterruptedly from side to side of the car, cover strips secured thereto throughout "their entire length and thereby forming carlines, the ends of said roof sheets and cover strip's'being'turned down outside said side plates and rigidly secured thereto, said side plates conforming to the under sides of the roof sheets and supporting them adjacent to their ends, whereby bending of'the roof sheets at'their end angles is prevented.

5. In a car roof, the combination of adjacent metallic roof plates extending transversely of the car and provided on their'adjoining edges withcxternal vertical flanges, said flanges extending uninterruptedly from side to side of the car and increasing in depth from the car sides inwardly, a U- shaped cover strip fitted over said flanges and rigidly secured thereto throughout'th'eir entire length, said flanges and cover strip forming a carline, lengthwise members along the eaves,-and means for securing'the endsof said cover strip and the ends of said roof sheets'thereto, whereby said cover strip and flanges support and stiflen said roof'tra'n'sversely'of the car and cause said lengthwise members to "function therewith.

6. In a car, in combination with metal side plates, metal roof plates arranged side by side crosswise or" the car and bent down over the side plates at their ends, the side margins of said roof plates being flanged up, seam covers of inverted U-shape covering adjacent side marginal flanges of said r'oof plates, said seam covers being rigidly "secured to said flanges to form carlines and hav ingtheir'ends turneddmvnover theside laea eee plates, the downtnrned ends of said seam covers and roof sheets being secured to said side plates.

"1'. lln a car, in combination With metal side plates each having a Vertical member and a substantially horizontal member extending inward from the top of the vertical member, metal roof plates arranged side by side crosswise of the ear and bent down over the side plates at their ends, the side margins of said root plates being flanged up, seam covers of inverted U-shape covering adj aeent side marginal flanges of said roof plates, said seam covers being rigidly secured to said. flanges to form earlines and having their ends turned down over the side plates, the top members of said side plates conforming to the under surface of the-roof plates adjacent thereto, and the downturned ends of said seam covers and roof sheets being secured to said side plates.

In testimony whereof, l have hereunto set my hand.
